Similar reference characters refer to similar parts throughout the several views of the drawings and specification. I

The improved sink construction, as generally illustrated in Figs. 1, 2 and 3, comprises a metal clad table section a which has'one or more sink wells b positioned and arranged therein as may bev desired. The metal clad table section a presents side drain portions 11' at each side of the sink well b, a front ledge portion a" extending at the front of the sink well I), and a rear ledge portion a' extending along the rear edge of the sink well I).

The table section a merges smoothly into a rear splash section c which may rise any desired distance to protect the building wall adjacent to which the sink is mounted. The front edge of the table section a merges into a downwardly extending apron section d, and the side edges of the table section a merge into downwardly extending apron sections 6. The vertical splash section 0 merges into a horizontally extending shelf section ,1 and into vertical end sections g. The front edge and the side edges of the table section are surrounded by a raised rim h approximately to A1 of an inch in height and adequate to prevent liquids deposited upon the table section from overflowing to the fioor. Shoe sections i may be secured to the rear corners of the sink to further stiffen and strengthen the construction and give the sink a finished appearance. The rear ledge portion a' of the table section a may be provided with suitable openings 9' for the convenient attachment of faucets and like plumbing fixtures. Sinks of the type generally above described may be economically fabricated and constructed to provide a highly serviceable and long-lasting construction of marked beauty and appearance, from a metal facing sheet m of relatively light gauge metal, preferably from a stainless steel sheet, which need not have a greater thickness than 18 gauge. The metal facing sheet is backed up, reinforced and stiffened by fibrous facing panels or sections 12 which may comprise laminated plywood, or other hard and durable fibrous sheet material, such as Masonite and like serviceable sheathing, used in the building industry. I

The metal facing sheet m is cut and shaped into the general form as illustrated in Figs. 1 to 7 inclusive to provide the table section I and the splash section 2 joined by a curving bend 3. The.

front edge of the table section I of the metal sheet is bent upwardly at an angle to form a rim forsection i of the metal facing sheet, and if de- I sired two such sink well openings in spaced relationship may be provided. The sink well opening 8, cut in the table section I of the metal sheet, is defined and surrounded by a downwardly inclined flange portion 9 terminating in a downturned lip portion l8 having a slightly rounded curvature, the lip portion In terminating in a square cut edge H. lip portion It of the metal sheetprovide means for the attachment of the sink well I), as will be more fully explained hereafter. The metal table section I presents side drain portions I2, a'front ledge portion I3, and a rear ledge portion l4 extending between the down-turned flange portion 9 and the surrounding rim formations and 5.

The metal facing sheet is also provided witha front apron section l5 extending downwardly from the front rim formation 4, and a front flange section l6 inturned along a bend line I! which parallels the raised front rim formation 4.

An inturned lip portion l8 extends from each end of the front flange section I5 as shown in Fig. 5. Each end 59 of the front flange section It is preferably out at a 45 angle. 7

A side apron section 2!] .extends downwardly from the side rim formation 5 and is provided with an inturned side flange section 2| which is inturned along a bending line 22 which parallels the adjacent raised side rim 5. The front end of g each side apron section 20 is provided with an in- The flange portion 9 and turned lip portion'23' as shown in Fig. 5. The

front 'end- 24 of eachsideflange section 2| is'also preferably cut on a'miter as shown in Fig.5.

The splas'h'section 2has a side edging section 26 at each end thereof which, during fabrication of the sink, will be bent-rearwardly along a bending lines? which issubstantially in alignment with the side forming rims 5 of the tablesection l. Each side edging section 26 has an inturned flange section 28 bent along the vertical bending line 29 as shown in Figs. Band 7. The splash section' 2 is provided-witha top shelf section 32 The upper end of each-side edging section 26- of the splashpanel is provided with an inturned lip portion 313 which abuts against a similar lip portion 34'extending from the adjacent end of the top shelf section 32 as shown in Fig. 6. The upper end 3| of each end flange section .28-is cut on a bias; and the adjacent end 31 of the flange section 35-of thesplash-section 2 is likewise cut on a-bias.

The fibrous backingsections'p are adhesively secured to the-underside of the metal facing sheet m. The backing sections may be approximately inchin thickness and may be formed of laminated plywood, hard pressed fibre, composition board, or like durable and strong fibre sheeting. The fibrousbacking comprises a table backing section 4| adhesively secured to and covering the under face of the table forming section i of the metal facing sheet; As shown in Figs. 4-

and 10, the-table-backing section 4! has a sink well opening cu-ttherein which is slightly larger than the sink wellopening 8 in thetable forming metal section I, so-that the metal flange portion 9 overhangs the-retracted edge portion 56 which defines the sink well opening in the backing section 4|, the overhanging flange 9 of the metal sheet thus providing means for securing the sink well structure U to the table forming section 1 of the metal sheet. As thus constructed, the drain backing portions 42 provide stiffening support for the drain board sections 12 f the metal sheet, while the front backing portion 13 I and the rear backing portion 44 provide support for the front ledge portion-l3 and therear ledge portion Moi the table forming section l of the metal sheet.

A front apron backing section 45 covers and is bonded to the rear face of the front apron section l of the metal sheet and extends between the front rim formation l'and the bend line ll of the metal sheet as shown in Fig. 3. The upper edged! of the apron backing section 45 has a rounded contour to snugly seat against the rear face 'of'the raised rim formation l of the metal sheet, andmay be bonded thereto by means of a suitable adhesive. The vertical ends 45 of the front apron backing section 45 are preferably cutzon a miter and are covered by the overlying inturnedlip portions it of the metal sheet, as shownmore particularly in Fig. 5. The inturned front flange section I 6 of the metal sheet may be covered by a backing section 48 bonded thereto by a suitable adhesive. The adjacent front edges of the front apron backing section 45 and the flange backing section 48' are cut on a miter to' provide a mitered joint 49 as shown in Fig, 3. Each end of the flange backing section 48 is cut 6 on a miter and terminates in line'with the ad jacent mitered end IQ of a the inturned metal flange section IS.

A side apron backing section 58, as shown' in Fig. 2, covers and isbonded to the rear face of each side apron section 20 of the metal sheet.

The upper edge 52 of each side apron backing: section 5!! possesses a semi-rounded or biased 1 contour to snugly seat against the underside of the raised metal rim formation 5, and thus provides a firm backing therefor. The upper round-- ededgedlmay-also be adhesively bonded to the The front end 5% of each side backing section 50 is cut on a 45 miter, and-is coveredby the overly-- underside of the raised rimformation 5.

inglip portion 23 of the metal sheet, as shown more particularly in Fig. 5.- It will be noted that the lip portion l8 of-the front apron section'of the metal sheet and the adjacent lip portion'23- of the side-apron section of the metal sheet are in face-to-face abutment. The joint 1 therebetweenmay be covered by a solder seam- 4 which is burnished and polished to give the front corner edge a finished appearance. The intur-ned flange section -21 of the metal sheet, asshown in Figs.

2 and 4, may be covered by a plywood backing section 53 which may be adhesively bondedalong a mitered joint 55 to the adjacent side apron backing section '59. The front end of the flange backing section 53 maybe cut ona miter in line with the mitered end 24 of the'intur-ned flangesection 25 of the metal sheet as shown in Fig. 4.

A splash backing section '52 and-ashelfback ing section fiscover and are bond'ed'to the rear face of thesplash section 2- andshelf'section: 32 of the metal sheet, as shown moreparticularly in Fig. 3. The lower-edge 63 ofthe splash-backing section 62 is spaced-from-the adjacent rear. edge E3 of the table b'acking sectionifil, leaving.

mitered 30mm with the. adjacent vertical edger also cut on a miter and coveredibythe inturned lip portion 3a of the metal sheet. The adjacent lip portions 3 5 and 3s of the metal sheet are in face-to-face'contact and may be firmly bonded together by a seam of solder or welding metal applied to the horizontal corner edge of the shelf section, as shown in Figs. 1 and 6. The adjacent ends of the side flange backing section 69 andthe top flange backing section 69 may be cut'on a 45 angle in line with the beveled end 3| of the metal flange section 28 and the beveled end 3'5 of the metal flange section 35, as shownmore particularly in Fig. 6.

The adjacent J In the construction above described it will be noted that the table forming section I of the metal sheet is firmly stiffened and supported by the table backing section til, the front apron section I and front rim formation 4 of the metal sheet is supported and reinforced by the front backing section 45, and the side apron sections 20 and the side rim formations 5 of the metal sheet are supported and reinforced by the side backing sections 55. The main splash section 2, the top shelf section 3.2 and the end sections 26 of the metal sheet are firmly and rigidly supported and reinforced by the main splash backing section 52, the shelf backing section 64 and the end backing sections fi'i respectively.

The table forming section a of the sink is further stiffened and reinforced by a front wood edging strip I5 which is inserted under the inturned front flange I9 and extends the full length of the sink as shown more particularly in Figs. 4 and 5. The wood edging strip 15 may be adhesively secured to the adjacent backing sections 4|, 4'5 and 48, and the front flange section I6 may be secured to the wood edging strip 75 as by screws or nails 16. A Wood side edging strip TI is inserted under each of the inturned side flange sections 2!, and extends the full width of the table section of the sink. as shown more particularly in Figs. 4 and 5. Each side edging strip 11 may be adhesively secured to the adjacent backing sections dI, 50 and 53, and may be secured to the adjacent inturned flange section 2 as by screws or nails 16.

A wood edging strip 18 may be set to extend under the inturned top flange 35 of the splash section 0 as shown more particularly in Figs. 3 and 6, preferably extends the full length of the splash section and is secured to the inturned top flange section 35 as by screws or nails "I6. A side edging strip I9 of wood is inserted under each of the inturned and flange sections 28 of the splash panel 0 and is secured in position as by screws or nails I6 as shown in Figs. -6 and 7. The top edging section 18 and the side edging sections 19 may be additionally secured in position by adhesive applied to the adjacent areas of the splash backing section 62, shelf backing section 64, end backing sections 61 and flange backing sections 60 and 69. Thus the table forming section a and the splash forming section 0 of the sink are additionally stiffened and reinforced by wood edging strips which positively prevent deformation of the sink construction.

The splash section 2 of the metal sheet is bent to extend substantially at right angles to the table forming section I thereof along the curved bend 3 as shown in Figs. 1 and 3. The bend 3 has a rounded curvature, approximately inch in arcuate length. A wood stiifening bar H having a rounded edge contour i2 is snugly fitted against the rear face of the rounded metal bend 3, and may be adhesively secured thereto. The outside faces 13 of the stiffening bar extends substantially flush with the adjacent inturned flange sections 2| and 28 of the metal facing sheet. The other two side faces "M of the wood stiffening bar II are so formed as to firmly abut against the adjacent ends of the side stiffening strips I? of the table forming section and the side stiffening strips 79 of the splash forming section, to thereby support and retain the splash panel c in the desired right angle relationship with respect to the table section a of the sink.

The sink well b may be formed from stamped sheet metal, preferably stainless steel, of somewhat heavier gauge than the panel forming metal sheet m. The sink well may be of any desired shape or form designed to flt within the well opening 8 of the table forming metal sheet. The sink well is initially formed as shown in Fig. 8 from a single sheet of pressed metal to present a bottom forming wall BI having a suitable drain opening 82 to which the sink drainage fixture is to be secured. The sink well D is enclosed by side enclosing walls 83 of any desired depth, which terminate in an outwardly flared flange portion 84. Prior to the attachment of the sink well to the table forming section of the sink, an off-set formation is formed in the enclosing side-walls 83 adjacent the outwardly flared flange portion 84, the off-set formation 85 being shaped to present a shoulder portion 86 as shown in Fig. 9. The inside faces of the laterally flared flange portion 84 and off-set formation 85 are shaped in close conformity with the contour of the flange portion 9 and down-turned lip portion In of the metal table facing section I of the metal sheet.

A band of soldering or welding metal 81 i deposited upon the outwardly flared flange portion 84 of the sink well as shown in Fig. 10, and the outwardly flared flange portion 84 is then pressed into firm contact with the metal flange portion 9 and lip portion II] of the metal table section I of the sink as shown in Figs. 10 and 11. When a soldering or welding heat is applied to the adjacent flange portions 9 and 84 by the use of electrical contact elements, the soldering or welding metal 87 becomes spread between the flange portions 9 and 84 to integrally bond the flange portions together. The welding or soldering metal will flow uniformly between the adjacent flange portions 9 and 84 and the adjacent surfaces of the lip portion If! and the off-set formation 85 as shown more particularly in Figs. 11 and 12 to provide a leak-proof seal, with the terminal edge I I of the metal facing sheet snugly abutting the shoulder portion 86 of the sink well. A smooth and even joint is thus made, with the inside face of the lip portion II flush with the inside face of the enclosing walls 83 of the sink well, so that no sharp corners or edges are presented to the user of the sink. The inclined flange portion 9 also facilitates the drainage of waste liquids into the sink well from the drain board areas a, a and a. The sink well can thus be attached to' the metal table facing section I of the sink economically and expeditiously to provide a leak-proof joint therebetween and to provide a construction which is free from sharp edges and corners, which facilitates drainage, and which is strong and lasting in use and attractive in appearance.

There is illustrated in Fig. 16 a sink well having a somewhat modified form of upper rim portion, wherein the flange portion 84 of the sink well shown in Fig. 8 is shaped to a generally rounded curvature 84 which curves smoothly into the off-set formation 85 and the shoulder portion 86. Thus when the upper rim portion of the sink well b is applied to the table section, the down turned lip portion It and the inclined flahge portion 9 of the metal facing sheet will snugly seat against the off-set formation 85 and the shoulder portion 86 of the sink well, and at the same time leave a slight gap 81' between the rounded flange portion 84' of the sink well and the adjacent, underface of the inclined flange portion 9 of the metal facing sheet as shown in Fig. 17. The gap 81' may be provided to facilitate the in-flow of'the soldering or welding metal 81 between the rounded flange portion 84 of the sink well and the inclined flange portion 9 and the lip portion is of the metal facing sheet.

To furtherenhance the bond between these flange portions, small spaced holes 3i? maybe punched in the rounded rim portion 3d of the sink well into which holes the soldering or welding metal 8'? may flow. By adopting this modification, a firm metallic bond between the rounded rim portion 8 3' and the off-set formation of the sink well, and the inclined flange portion 9 and the lip portion of the metal facing sheet, may be expeditiously achieved. The filler boards I 90 may'then be applied and the joint between. the

side walls of the sink Well and the filler boards at and the table backing section 44 may be filled with a suitable mastic 85. as shown in Fig. 18,

To further stiffen and strengthen the construction, the under side area of the table section of the sink between the front edging strip "f5, side edging strips if and rear stiffening bar ll. may be filled in with wood or fibrous filler boards 1 90 as shown more particularly in Figs. 2, 3 and 5. The front edging strip '55, the side edging strips it and the rear stiffening bar ll may be notched or grooved as at 9| to lock the filler boards 99 thereto, The filler boards as may also be adhesively secured to the edging strips l5 and IT, to the stiffening barl' i, and to the table backing section el, Wood or fibrous. filler boards 92, shown in Figs. 3, 6 and 7, may be applied to the rear face of the splash panel (2. The filler boards 92 preferably have a notched interlock'as at 93 with the edging strips 18 and '59 of the splash panel. The filler boards 92 may additionally be adhesively secured to the edging strips l5 and 19 and to the rear face of the splash backing section 62. additional reinforcing, insuring a finished sink of great strength and rigidity, and yet relatively light in weight. Suitable water-proof packing 88, such as a bituminous or gummy compound, may be packed between the outside faces of the side enclosing walls 33 of the sink well D and the ad- ,iacent edges of the filler boards 90, and the surrounding-edges 56 of the table backing section 5i as shown inFigs. 5 and 6.

In forming the sink from-a single'sheet of facing metal in inthe manner above described, the ends of the wood stiffening bar li would not be covered by metal sheeting. Where the sink sides are to abut against a wall or cabinet, metal coverage of the ends of the stiffening bar H may be unnecessary. However, the ends of the stiffening bar 5i may be easily covered by the pro vision of a shoe 1 formed from a stainless steel sheet shaped as shown in Figs. 1, 5 and 6 to present a generally triangular shaped side facing portion 95, a vertical flange portion 9i and a horizontal flange portion 98. The sheathing shoe 2' is so shaped that the facing portion $56 will fully cover the exposed end of the stiffening bar 'il. The vertical flange Ell of the sheathing shoe *5 seats over and is secured to the rear face it of the stiffening bar it and the horizontal flange 98 fits over and is secured to the horizontal face 13 of the stiffening bar "it.

Stainless steel sinks constructed in accordance with this invention are particularly designed for mass production at a price well within the reach of the modest home owner, and at a greatly reduced cost as compared with stainless steel sinks heretofore provided. These sinks are lasting in The filler-boards'fiii and 92 provide use, aredesigned to be supported upon and easily fitted to. any desired cabinet structure and to the interior wall of the building in which they are placed, and provide va construction of lasting utility, highlyattra'ctive and appealing in appearance and finish.
